No, not necessarily... Javascript actions on the main page, including form submits or timers can load a new page in the hidden IFRAME. The new page in the IFRAME could be a php page, that generates new javascript code which is then run when the page in the IFRAME is loaded. The javascript code on the page in the IFRAME calls functions in the code on the main page, or changes values in the data on the main page, thus updating the main page without reloading.
